Contemporary dishwashers for use in a typical household include a tub defining a treating chamber in which utensils are placed for cleaning of the stored utensils during an automatic cycle of operation, such as a wash cycle. Dishwashers include spray systems having one or more sprayers which are supplied with liquid by supply conduits. Wash liquid is recirculated through the treating chamber by a wash pump which fluidly couples the treating chamber to the supply conduits to recirculate liquid in the treating chamber.
Some dishwashers may be provided with a separate, dedicated tank for storing liquid captured from the wash tub during a previous cycle of operation or a phase of a cycle of operation. The tank can be provided within the housing of the dishwasher. The stored liquid is then used in the same wash cycle or a subsequent wash cycle.
